Consistent – a system of equations with at least 1 solution(Graphs meet at 1 point or are on same line)
Consistent can be Independent – with exactly 1 solution OR
Dependent – with infinite number of solutions
Inconsistent – No Solution
For slope-intercept form equations, y=mx+b, with slope m and y intercept b,
different slopes – exactly 1 solution
same slope but different y intercept – no solution(parallel)
same slope and same y intercept – infinite solutions
